Stones to Pounds Converter
Enter stones, pounds, or a mixed weight such as 11 st 4 lb. Convert in either direction and see kilograms as a secondary reference.
Exact relationship: 1 stone = 14 avoirdupois pounds.
A bare number uses From. A typed or pasted st, stone, lb, or pound label sets the direction; mixed values such as 11 st 4 lb are supported.
How to convert stones to pounds
Pounds = stones × 14. The avoirdupois relationship is exact: 1 stone equals 14 pounds. For example, 3 st equals exactly 42 lb.
How to convert a mixed stone-and-pound weight
Convert the stone portion to pounds, then add the remaining pounds. For 11 st 4 lb, calculate 11 × 14 = 154 lb, then add 4 lb. The result is exactly 158 lb.
How to convert pounds back to stones and pounds
Stones = pounds ÷ 14. The whole-number quotient gives the stones, while the remainder stays in pounds. Dividing 158 lb by 14 gives a quotient of 11 with a remainder of 4, so 158 lb is 11 st 4 lb.
A decimal-stone result expresses the same weight another way. Keep the quotient-and-remainder form when a label, form, or conversation expects separate stone and pound values.
Kilograms are a secondary reference
The converter also shows kilograms using the exact international avoirdupois definition 1 lb = 0.45359237 kg. The stone-to-pound result remains the primary answer; the kilogram value helps compare the same weight with a metric record.
Avoirdupois scope and input boundary
This page uses the ordinary avoirdupois stone and pound. It accepts stones, pounds, or a mixed value such as 11 st 4 lb, but it does not reinterpret troy units, liquid measures, or another weight system as avoirdupois values.
Kilograms are output only. If kilograms are the value you already have, use the related kilograms-to-pounds converter instead of entering kg here.
